I-stafFolds yiqonga lokusebenza elakhiwe ukuqinisekisa inkqubela phambili egudileyo yeenkqubo ezahlukeneyo zokwakha. Njengenxalenye engenakuphikiswa neeprojekthi zokwakha, imisebenzi yalo yokwakha ibalulekile kuyo yonke iprojekthi.
Imigangatho yokuqala, esemgangathweni yesakhiwo se-screfold
1. Umbhobho wentsimbi
. Kufanele ukuba ibe nesatifikethi somgangatho wemveliso kunye nengxelo yokuhlola. Ezona zinto zikhutshiweyo zikhutshiwe kufuneka zitshintshwe kwaye akufuneki zisetyenziselwe ukwakha isakhelo.
. Akufuneki kubekho ukulumkisa okukhulu, ukugoba, ukungqubana, ukonakaliswa, okanye ukuqhekeka. sebenzisa.
(3) Imibhobho yentsimbi idityaniswe nepeyinti ye-anti-rust. Izibonda ezithe nkqo kunye neepali ezithe nkqo zipeyintwe ngepeyinti ye-anti-rust etyheli, kwaye inkxaso ye-Scissor kunye neeTubs zezandla zipeyintiwe ngepeyinti ebomvu nemhlophe. Elona xesha liphezulu lombhobho ngamnye wentsimbi akufuneki ibe ngaphezulu kwe-25 kg. Kunqatshelwe ngokungqongqo ukubaleka imingxunya kwimibhobho yentsimbi.
.
I-2. Abakhethi
(1) Izithuthi ezitsha kufuneka zibe nelayisensi yemveliso, isatifikethi semveliso yemveliso, kunye nengxelo yokuhlola. Izilonda zakudala kufuneka zihlolwe umgangatho ngaphambi kokusetyenziswa. Abo banee-rocks okanye izigqibo azivumelekanga ngokungqongqo ekusebenziseni. I-bolts nge-slipping kufuneka itshintshwe. Zombini ezi zinto zintsha kunye nezidala zifanele ziphathwe ngenkani. Gqibezela iindawo ezinqabileyo kakhulu kunye nezixhobo ezonakalisiweyo kwaye zithathe indawo ye-bolts ngexesha. I-oilts i-bolts iqinisekisa ukuba lula ukusetyenziswa.
. Xa i-fattener iqaqamba umbhobho wentsimbi, owona mgama usezantsi phakathi kwezinto ezivulekileyo kufuneka ungaphantsi kwe-5mm. Abantu abasetyenziswayo akufuneki bonakaliswe xa i-bolt yokuqinisa amandla afikelela kwi-65n.m.
Okwesibini, iinkqubo zokwakha, iindlela, kunye neemfuno zokufuduka
(1) IFOMU YOKUGQIBELA
Le projekthi isebenzisa i-16 # I-Bhulu ye-Bhulued call i-pole kunye nomqolo ophambeneyo ophambeneyo. Umgama wenyathelo lomgama wecawa ye-cantilever yi-1.8m umgama wezibonda yi-1.5m, kwaye umgama phakathi kwemiqolo engaphakathi kunye ne-poles ye-0.85m; Iibhloko ezincinci ezinqamlezileyo zibekelwe ngezantsi kweendawo ezinkulu ezinqamlezileyo, umgama phakathi kweendawo ezinqamlezileyo zangaphandle yi-0.9m, kunye nomgama ophakathi kweendawo ezinkulu ezinqamlezileyo yi-1.8m. I-therbar ethe tyaba yongezwa embindini webar encinci.
(2) Inkqubo yokwakhiwa kweScreen kunye nenkqubo yokwakha
I-1. Ukubekwa kwe-Shelf cantworver Beams
.
.
. Emva kokuba i-bemms ibekwe, iingcingo zitsalwa kwaye zibekwe ecaleni, emva koko zenziwe zazenzela imivalo yentsimbi.
.
I-2. Ukulandelwa kokukhula
Setha izibonda ezithe nkqo enye nganye ukusuka kwisiphelo sekona yesakhiwo → Beka i-pole ethe tye (i-pole enkulu ethe tyaba), kwaye uqinisa i-pole ethe tye (kwaye uyibambe nkqo kwi-3-4 poles ethe tye, ukufaka Imivalo enkulu ethe tyaba kwinyathelo lokuqala (inika ingqalelo ekukhawulezeni nge-vertical ye-vertic) IZikhundla ezihambelana
I-3. Izinto zokuqaphela xa kubeka isitali
.
. Emva kokuba inyathelo ngalinye le-scalfoldang lakhiwe, lungisa umgama wenyathelo, umgama othe nkqo, umgama othe tye, umgama othe tyaba, kunye nokuthe tyaba kwezibonda ukuqinisekisa ukuba bayazifezekisa iimfuno, emva koko bacwangcise inyathelo le-Wall kunye nenyathelo elidlulileyo.
.
(3) Iindlela zokwakha kunye neemfuno
I-1. Iimfuno zokumisela isibonda esitshisayo: Ipole etyhefu ye-ixesha elide ilungisiwe kwi-vele engaphezulu kwe-100mm ukusuka kwi-100mm kude ne-Epifulium isebenzisa i-epitium enesiseko. Intonga ethe tye ilungisiwe kwisibonda esithe nkqo kwangoko ngaphantsi kwentonga evuthayo isebenzisa i-Angle.
2. Iimfuneko zoMgangatho wokuSebenza:
. Isibonda esithe nkqo kufuneka ubuncinci sibe yi-1.5-1.8m ngaphezulu kunokuba sisebenza.
. Abafakeli be-butt kwizibonda ezithe nkqo kufuneka bacwangciswe ngendlela ecekisekayo. Ukudibana kwezibonda ezimbini ezikufuphi kodwa ezithe tye akufanelekanga ukuba zibekwe kulungelelwaniso. Umgama ojijekileyo kwi-ndlela yokuphakama kwamalungu ayingabi ngaphantsi kwe-500mm, kunye nomgama phakathi kweziko lokudibana nganye kunye nendawo ephambili engabinayo i-1/3 yomgama.
I-3. Iimfuneko ezinkulu zokwenza i-crossbar:
. Ubude bayo bungabi ngaphantsi kwe-3 spans. Kwinqanaba elifanayo le-scaffolding, imivalo enkulu ethe tyaba kufuneka ijikelezwe macala onke kwaye ilungiswe kunye ne-wanile yekona yangaphakathi nangaphandle.
(2) Iindlela ezineenkcukacha zokudibanisa okukhulu kwe-bar Amalungu e-Butt kufuneka acwangciswe ngendlela ecekisekayo kwaye akufuneki ibekwe kwisithuba esinye. Umgama othe tyaba phakathi kwamalungu akufuphi akufuneki ungabi ngaphantsi kwe-500mm. Amalungu kufuneka aqhagamshelwe kwizibonda ezithe tye. Umgama akufuneki ube ngaphezulu kwe-1/3 yesithuba sepali.
4. Iimfuneko zokuLubekwa kwiindawo ezincinci:
Ibar encinci ethe tyaba kufuneka ifakwe kwindawo ephambili (i-inversection ye-pole ethe nkqo kunye ne-bole ethe tyaba) kwaye ifakwe kwindawo enkulu) kwaye ifakwe kwindawo ephezulu ye-Angle eThengisisayo isebenzisa i-Angle. Ubude obungaphandle bokuphela bungabi ngaphantsi kwe-100mm, kwaye ubude bokuphela kwesiphelo ngokuchasene nodonga aluyi kuba ngaphantsi kwe-100mm. Ngaphantsi kwe-200MMM, umgama oya kwindawo yokuhlola udonga akufuneki ube ngaphezulu kwe-100mm. Umgama phakathi kwe-axis yentonga kunye nendawo ephambili ayifanele ibe ngaphezulu kwe-150mm.
I-5. Iimfuno zokufakelwa okukhawulezileyo:
.
. Kuya kufuneka kuqinisekiswe ukuba i-fastteri nganye ihlangabezana neemfuno.
.
.
.
I-6. IIMFUNO ZOKUGQIBELA phakathi kwesakhelo kunye nolwakhiwo lokwakha
. I-tie rod kufuneka isethwe kwiPole ngokuthe nkqo kwaye utsala izibonda zangaphakathi nangaphandle ezithe nkqo ngexesha elinye. Iintonga ze-tie zicwangciswe ngokuthe tyaba. Xa bengakwazi ukucwangciswa ngokuthe tye, isiphelo esinxulunyaniswa nesisa kufuneka sidityaniswe kwindawo esezantsi kwaye hayi phezulu.
. I-stafFoddeng kufuneka idityaniswe ngokuqinileyo kumzimba ophambili wesakhiwo. Xa useta, zama ukuba kufutshane nendawo ephambili njengoko kunokwenzeka, kwaye umgama ukusuka kwindawo ephambili akufuneki ibe ngaphezulu kwe-300mm. Kufuneka ihlelwe kwi-rossbar yokuqala enqamlezayo ezantsi kwilungiselelo elenziwe ngedayimane.
.
7. Ungayibeka njani isikere
. I-scacto nganye iqhagamshelwe kwi-5 pole ngokuthe nkqo. I-Scissor Braces kufuneka kwakhiwe kwangaxeshanye kunye nezibonda ezithe nkqo, izibonda ezinkulu ezithe tyaba, izibonda ezincinci ezithe tye, njl.
. Umgama phakathi komgca ombindi we-fasttener ejikelezayo kwaye i-node ephambili ayifanele ibe ngaphezulu kwe-150mm. Ukongeza ekwenzeni iziphelo ezibini zentonga ethambekele kwi-pole ethe nkqo, amanqaku angama-2-4 kufuneka ongezwe phakathi. Umgama wonxibelelwano phakathi kwesiphelo esisezantsi sentonga ethambekileyo kunye nesibonda esithe nkqo asiyi kuba ngaphezulu kwe-500mm. I-angle yotyekelo phakathi kwePole Ext nomhlaba kufuneka iphakathi kwe-45 ° -60 °.
. Izintyathuna ezintathu ziya kulungiswa ngokulinganayo, kwaye ezona ndawo ziya kufakwa phezu kombhobho wentsimbi ngaphantsi kwe-100 mm.
I-8. Ukubekwa kweeplanga zokufuduka
.
. Iibhloko ezimbini ezincinci ezinqamlezileyo kufuneka zisetwe phantsi kwamalungu eebhodi ze-scafding zibekwe ecaleni kwenye. Ubude boLwandiso lweeBhodi zeScAffield yi-130 ~ 150mm. Isixa sobude bobude beebhodi ezimbini ze-stafFold akufuneki zibe ngaphezulu kwe-300mm; Xa iibhodi zescreyiding zigqunywe kwaye zibiwe, amaziko kufuneka axhaswe kwi-crossbar encinci, ubude obugqithisileyo kufuneka babe ngaphezulu kwe-200mmbar, kwaye ubude bexesha elincinci lokungabi ngaphantsi kwe-100mm. Iibhodi ze-stafFodding zimele zibekwe ndawonye. I-ScafFold Probe ilungisiwe kwi-rossbar enkulu ene-18 # wire yentsimbi. Iibhodi zokufuduka kwiikona kunye nokuvuleka kwe-Ramp ekuvulekelwa kufanelekile ukuba zidityaniswe ngokuthembekileyo kwiibhloko ezincinci zokuthintela ukutyibilika.
(3) Umaleko wokwakha kufuneka igutyungelwe ziibhodi zesakhiwo.
9. Ukuvalwa kwangaphakathi kunye nokukhuselwa kwangaphandle kwesakhelo sesakhelo
.
.
. Le projekthi isebenzisa ubume benkuni yokuvalwa.
.
I-1. Ukuphambuka ngokuthe tye: Ukuphambuka kwe-verication yepoli akufuneki kungabi ngaphezu kwe-H / 300, kwaye kwangaxeshanye, ixabiso lokuphambuka akufuneki libe li-75mm. Ukuphambuka akuyi kuba nkulu kune-H / 300 kwaye akuyi kuba ngaphezulu kwe-100mm.
2. Ukuphambuka okuthe tye kweendawo ezinkulu ezinqamlezileyo: Ukuphakama komphakamo phakathi kweziphelo ezimbini zebar enkulu enqamlezileyo ayinakudlula kwi-20mm. Ukuphambuka okuthe tye kweendawo ezinkulu ezinqamlezileyo akufuneki zibe mkhulu kune-1/300 yobude bebonke, kwaye ukuphambuka kwengqolowa kobude bonke akufuneki kungabikho ± 100mm. Ukuphakama phakathi kwemivalo emibini ethe tye yelitye elifanayo nengabi ngaphezu kwe-10mm;
